无燃烧与爆炸危险的环境中。
燃烧与爆炸都是化学反应，必须具备纤维粉尘达到一定浓度、遇到一定点燃能量、在空气中有一定含氧浓度（％）这三个条件。
Both inflammation and explosion are chemical reactions, for which three prerequisites are required, i. e. certain fibre dust density, certain ignition energy andcertain oxygen density(%);
能燃烧，蒸气与空气形成爆炸性混合物，爆炸极限7% - 73%(体积)。
Can burn, vapor and air to form an explosive mixture, the explosion limit of 7%-73% (volume).
使用时燃气预先与空气充分混合，再进行燃烧，使燃烧进行得剧烈而充分，绝对无任何爆炸危险。
Use of gas and air pre-mixed and then burning to intense burning was carried out and the full and absolute absence of any explosion hazard.
氢气与氧气混合时会发生爆炸性燃烧。
